What should be done after form removal when a release agent was used?

Explanation:
When forms come off, you want to remove any film of release agent from the concrete surface. The release agent’s job was to prevent sticking, but leaving residue behind can interfere with how the surface finishes look and perform later—it can mask the texture imparted by the form, cause staining, and hinder adhesion of coatings or sealers. Cleaning off that residue reveals the intended texture and prepares the surface for any subsequent finishing steps. Reapplying a release agent would create a barrier that can impede bonding, so it’s not appropriate after form removal. The key action is to remove the residue to expose the surface texture.
